## What is the purpose of the change This PR migrates legacy SourceFunction and SinkFunction implementations in table planner tests from the deprecated legacy APIs to the modern FLIP-27 Source API ## Brief change log - Migrated TableFactoryHarness.ScanSourceBase from SourceFunctionProvider to SourceProvider with DataGeneratorSource - Migrated TableFactoryHarness.SinkBase from SinkFunctionProvider to SinkV2Provider with TestSinkV2 - Implemented custom Source V2 in CommonExecSinkITCase.TestSource to preserve timestamp ordering - Updated BuiltInAggregateFunctionTestBase to use DataGeneratorSource instead of legacy SourceFunction ## Verifying this change Existing tests already cover these changes: - BuiltInAggregateFunctionTestBase: ModuleITCase, HashcodeITCase, MiscAggFunctionITCase, ArrayAggFunctionITCase, JsonAggregationFunctionsITCase, PercentileAggFunctionITCase - CommonExecSinkITCase: testStreamRecordTimestampInserterSinkRuntimeProvider and other timestamp-related tests - TableFactoryHarness: All dependent test cases using the harness framework All tests pass. ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): no - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: no - The serializers: no - The runtime per-record code paths (performance sensitive): no - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Kubernetes/Yarn, ZooKeeper: no - The S3 file system connector: no ## Documentation - Does this pull request introduce a new feature? no - If yes, how is the feature documented? not applicable -- This is an automated message from the Apache Git Service.
